Re: So
"last month"

: : SO "LAST
MONTH" - Out of date, out of touch. "CBS's Andy Rooney told an interviewer, 'The
only thing that really bugs me' about NFL coverage on TV 'is those damn women
they have down on the sidelines who don't know what the hell they're talking about.'
Replied National Organization for Women president Kim Gandy: 'Andy Rooney, like
my 9-year-old says, is so last month.'" From "Time" Oct. 21, 2002.

: Deliberate
or unintentional irony on the part of Ms. Gandy, I wonder? "(That's) so..." as
a dismissive descriptor with defined time periods, such as, "that's so 80's" or
"that's so last year" is in common enough usage on both sides of the Atlantic,
I believe. "So last month" is a nice twist on this, carrying as it does connotations
of the fickleness and ephemeral nature of media popularity and fashionability.
What with today's channel surfers, who have less attention span than a damaged
goldfish, I expect soon to see "he's so last week" or "that's so yesterday".

And
so you shall. I just saw "so last Thursday" in the paper. Fickle indeed...
